Description

I'm trying to upload a valid .glb file, and there are some problems:

• Using the method ->getMimeType() always returns 'application/octet-stream' instead of 'model/gltf-binary'
• Using the method ->extension() always returns 'bin' instead of 'glb'

In the Mime types, i can find these keys in the map and the reverse map so it should work:

        'glb' => ['model/gltf-binary'],
        'gltf' => ['model/gltf+json'],

How to reproduce

Try to upload a valid GLB and use ->extension() method.

For example:
Duck.glb

BrainStem.glb

Additional Context

You can check the GLB files that i mention are valid here: GLTF VALIDATOR

Doing something like this:

$fileToUpload = $request->file('file');
dd($fileToUpload->extension(), $fileToUpload->getClientOriginalExtension());

Displays "bin", "glb"
